--rcfile takes an argument.  It has to be followed by the name of the
rc file that you want bash to read.

When you write   --rcfile --login   you're telling bash that its rc file
is named "--login", and that it should read this file, instead of ~/.bashrc=
,
if it needs to read an rc file.

However, since you also gave the name of a script to execute, bash doesn't
need to read an rc file.  So, it simply ignores the   --rcfile --login
that you gave it, and just executes test.sh.

On the other hand, when you write   --login --rcfile test.sh
you are telling bash that its rc file is named "test.sh", and that it
should read this instead of ~/.bashrc if it needs to read an rc file.

But since you're using the   --login   argument, bash doesn't need to
read an rc file.  So, it doesn't make use of the   --rcfile test.sh
arguments.  You're basically just running   bash --login   .
